Imgur bad extension detection

[ReiFan49]

umm, as the title says... i tried to upload an activity with jpg, but it resulted that it reads as .png extension instead .jpg on the url, so the image won't load.

This is not related to the file type, since imgur converts the files. The problem is that we are currently blocked from imgur, so I'm discussing with the imgur staff to solve the problem. We've been exchanging emails and it should be fixed soon!
